On November 2, 2018 Intensity Therapeutics, Inc., a clinical-stage biotechnology company developing proprietary immune cell-activating cancer treatments, reported the completion of a $6.5 million Series B financing (Press release, Intensity Therapeutics, NOV 2, 2018, View Source [SID1234530618]).
Intensity plans to use the proceeds of the financing to advance the clinical development of lead product candidate INT230-6, a direct intratumoral injection that is currently being evaluated in a Phase 1/2 clinical study in patients with various advanced solid tumors. The Company intends to expand the study by adding clinical sites outside the U.S. and Canada, as well as adding combination arms with an anti-PD-1 antibody.

"The support from our investors in this round, who purchased stock at a 150 percent premium to our Series A financing, underscores the potential of INT230-6 and our proprietary DfuseRxSM technology discovery platform," said Lewis Bender, Founder and Chief Executive Officer of Intensity. "With this funding, we are well positioned to complete the ongoing Phase 1/2 study of INT230-6, including planned combination arms with an anti-PD-1 antibody, and initiate Phase 2a studies in specific tumor types next year. We look forward to further evaluating the safety and efficacy of INT230-6 to ultimately bring a novel, intratumoral, immune response-activating treatment to patients with refractory solid tumor cancers."

As the Company recently reported at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) 2018 Congress, preliminary data from the ongoing Phase 1/2 study demonstrated intratumoral injections of INT230-6 were well tolerated with no drug-related serious adverse events or dose-limiting toxicity in patients with advanced solid tumors. In addition, increases in circulating CD8 and CD4 T-cells and evidence of abscopal responses in non-injected tumors were observed. Preliminary data from this study will also be presented at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) 33rd Annual Meeting, which is being held November 7-11 in Washington, DC.

About INT230-6

INT230-6, Intensity’s lead product candidate designed for direct intratumoral injection, is comprised of two proven, potent anti-cancer agents and a penetration enhancer molecule that helps disperse the drugs throughout tumors and diffuse into cancer cells. INT230-6 is being evaluated in a Phase 1/2 clinical study (NCT03058289) in patients with various advanced solid tumors. In preclinical studies, INT230-6 eradicated tumors by a combination of direct tumor kill and recruitment of dendritic cells to the tumor micro-environment that induced anti-cancer T-cell activation. Treatment with INT230-6 in in vivo models of severe cancer resulted in substantial improvement in overall survival compared to standard therapies. Further, INT230-6 provided complete responder animals with long-term, durable protection from multiple re-inoculations of the initial cancer and resistance to other cancers. In mouse models, INT230-6 has shown strong synergy with checkpoint blockage, including anti-PD-1 and anti-CTLA4 antibodies. INT230-6 was discovered from Intensity’s DfuseRxSM platform.
